I don't think that switching to Intel graphics can be called a fix (even a temporary one) and isn't available for owners of many laptops that do not support nVIDIA Optimus. You are simply disabling the nVIDIA card this way and with it, all the advantages that it brings (higher graphics performance). This should be done anyhow if your laptop is Optimus- enabled and you don't need the dedicated GPU's performance. You can also install "prime-indicator" package from ppa:nilarimogard/webupd8 to switch quicker - it's not as good as automatic on-the-fly switching on Windows but it does its job.
However, a real solution has to be found which will let us use the nVIDIA cards with official nVIDIA driver (not the buggy and underperforming noveau) without this freezing. I don't mean to devalue Sebastian's advice, since it can indeed help many people who aren't interested in using dedicated graphics, but I want to make it pretty clear that this is not a fix or even a workaround, since it switches the graphics card completely. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1220426 Title: [nvidia-prime]Freeze while using touchpad To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-319/+bug/1220426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
